02 sensor help, part two :)

[malakia12]

ok guys, since it has snowed so much up here the last couple of days, I have not had a chance to take my car down to Delaware to get the O2 sensor problem checked out. I finally got my Peake research tool a couple days ago, and scanned my car and got these codes
Table 19
E1 > After Cat Fuel Trim Cyl #1-3
E2 > After Cat Fuel Trim Cyl #4-6
E6 > PreCat O2 Sensor slow response
EC > PreCat Fuel Trim Cyl #4-6

anyone have any idea what could be causing these codes? For those who don't know, I recently got high flow cats put on my car(I have headers), and European Performance extended the O2 sensors further to reach the cats just like everyone else has. We already replaced a faulty O2 sensor once, which gave me problems before. Do you think I have another faulty O2 sensor? I guess the E6 code would prove that right, since it is saying slow response?

Omes > did you get any of these codes when your shop mixed up the O2 sensors in your car?

They probably used the wrong wire-type to extend the probes.

what is the right one needed if you dont mind me asking? I am trying to get as many possible solutions gathered so when I take my car back I have something informative to tell them.

Regular steel wire...not copper.

yup....that sounds like the problem the previous owner of my cats had. He kept getting fault codes on the passenger side cat, and he had his installer rewire it two times (both times with new O2 sensors), but no luck. I used good quality steel wire (some suggested using aircraft grade, but no problems here so far). From what I've read up on before I took on the install, it seems as though most of the fault codes are from improper wiring. Which cats did you go with?

No man, sorry I have never seen those codes before, sounds like there are fuel trim problems that have arisen from the cats, maybe take it down to the stealership and get them to do an ECU reset with the GT1 and see what pops up from there. When my O2 sensors were mismatched I got misfire codes with fuel trim codes and lean/rich codes.

Omes.

thanks for the help guys

I will call the shop up today and ask them about what type of wire they ran and see what they say.

KP> they used Random Tech race cats
